A suspended chiropractor has been found to have been spying on his patients and exaggerating their diagnoses for financial gain.

Adelaide chiropractor Robert Marin was found 'unfit to practice' by a health practitioners' tribunal on 17 grounds of professional misconduct, Today Tonight reported.

The acts of misconduct included fixing cameras on patients using dressing rooms, taking X-rays of children under 12 without clinical reasons and pressuring clients to undress in X-ray and massage rooms while cameras were recording.

Also among the tribunal's findings were Marin eavesdropped on private conversations and exaggerated conditions so patients would commit to long-term treatments.

A number of the findings related to his re-invention as a weight loss consultant, in which he used 'questionable methods' to diagnose patients and provided costly, unlabelled weight-loss supplements, according to Today Tonight.
